* Noteworthy changes in release ?.? (????-??-??) [?]
+** Changes in behavior
+
+ The GZIP environment variable is now obsolescent; gzip now warns if
+ it is used, and rejects attempts to use dangerous options or operands.
+ You can use an alias or script instead.
+
+** Bug fixes
+
+ gzip -k -v no longer reports that files are replaced.
+ [bug present since the beginning]
+
+
+* Noteworthy changes in release 1.6 (2013-06-09) [stable]
+
+** New features
+
+ gzip now accepts the --keep (-k) option, for consistency with tools
+ like xz, lzip and bzip2. With this option, gzip no longer removes
+ named input files when compressing or decompressing.
+
+** Bug fixes
+
+ gzip -d no longer malfunctions with certain invalid data in 'pack' format.
+ [bug introduced in gzip-0.8]
+
+ When overwriting, gzip no longer acts as if you typed "y" when you type "n",
+ on some platforms when compiled with optimization.
+ [bug introduced in gzip-1.3.6]
+
+ zgrep no longer malfunctions with a multi-digit context option like -15.
+ Now, it passes that option to grep (equivalent to -C15) just as it does
+ for single-digit options. [bug introduced in gzip-1.3.12]
+
+ zmore now acts more like 'more', and is more portable to POSIXish hosts.
+
+
+* Noteworthy changes in release 1.5 (2012-06-17) [stable]
+
** Bug fixes
gzip -d now decodes and checks header CRC16 checksums as specified by
For example, now "(printf x|gzip; echo y)|gzip -dcf" prints "xy\n",
while before it would print "x<compressed data>y\n".
+ gzip -rf no longer compresses files more than once (e.g., replacing
+ FOO with FOO.gz.gz) on file systems such as ZFS where a readdir
+ loop that unlinks and creates files can revisit output files.
+
* Noteworthy changes in release 1.4 (2010-01-20) [stable]
* With --force, let zcat pass non gzip'ed data unchanged (zcat == cat)
* Added the zgrep shell script.
* Made sub.c useful for 16 bit sound, 24 bit images, etc..
-* Supress warnings about suffix for gunzip -r, except with --verbose.
+* Suppress warnings about suffix for gunzip -r, except with --verbose.
* On MSDOS, use .gz extension when possible (files without extension)
* Moved the sample programs to a subdirectory sample.
* Added a "Special targets" section in INSTALL.
